IMPROVEMENT IN BLEACHING TEXTILE FABRICS.

Specification forming part of Letters Patent No. 39,998, dated September 15,1863; antedated January 3, 1863.

' To aZZ whom it may concern:

iiir zmdogler in which the fabric to be bleachedis treated witlLceptain well-known liquors, all and every one of which are applied cold, and the effect of which is smrthat the bleaching of cotton and other textile iabricscaubc complctcd in from three (3) to three and one-halt ..A@L liours without injury to the fabrics, and

3' 11st nerfectly as h rtlie\m dirurry tediouse process.

To enable those skilled in the art to fully understand and correctly use my invention, I will proceed to describe it. 7 q

The different liquors which I use are solu-- t-ious of caustic soda, chloride of lime, and diluted sulphuric acid These liquors are apon'the goods for about fifteen minutes, when the same are removed and lightly washed or rinsed in clean water an operationiwhich requires another term of fifteen minutes.

Fourth. A solution of chlqififleafelillliwf 3 tion for the same length of time as above unare lightly washed, the whole operation requiring aboutthirty (30) minutes.

Fifth. A solution ofsulphpric aeid,a's above. The action of this solution on thegoods continues for fifteen minutes, when thcsa-me are removed and thoroughly washed. This operbe noticed that during the entire processall boiling operations or the use of warm or hot liquors areavoided, whereby much time and laborand the expenditure of fuel is saved.

-. For ordinary cotton goods the operation is half (3%) hours, and the goods are full as white goods bleached by the old process, which is not completed in the same number of days. My process is applicable, however, to bleach Twaddle. The goods are eiposed to this soluder No. 2, and on being removed from it they ation completes the whole process; and it will completed in. about three (3) or three and onelinen,'and also stockings, and, in fact, for the First. A solution of caust dja of about 3 heaviest goods-such as cantmrfiannel, marcold, and after the goods have remained in it for about half an hour they are removed and thoroughly washed in clean cold water-an operation which also requires about half an hour with the'proper machinery. Second. A solution. of gl lgride eLlipie of about 3 Twaddle. The goods are exposed to the action of this solution, which is also applied perfectly cold, for the time of about fifteen (15) minutes, and when removed from this solution they are again washed lightly for about fifteen minutes.

Third. A solution of splphuricacid of about 3 Twaddle. '.l.his solution is permitted to act hTwa hi solution is applied perfectly seilles, &c.and in all cases it is conducted perfectly cold, and the bleaching is effected without injury to the fibcrs.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isy The within-described process for bleaching textile fabrics by treating them with the ]i q- THEODOR SGHNEBELY.
